Pada kesempatan kali ini saya akan menjelaskan mengenai sebuah alat yang berfungsi untuk memonitor suhu menggunakan sensor LM35 dan kendali led via internet menggunakan aplikasi Blynk. aplikasi Blynk bisa didapatkan di handphone atau tablet dengan cara install pada play store di android atau app store di IOS. untuk lebih jelasnya berikut adalah program dan daftar komponennya NodeMCU was created shortly after the ESP8266 came out. On December 30, 2013, Espressif Systems began production of the ESP8266. NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. LM35 data or temperature can be shown on phone from anywhere. An Example of how can we read data through the virtual pin. By ARDUICREATE. Water Level Indicator Using Arduino. Wireless Water Level Indicator Using Ultrasonic sensor & Arduino is an amazing and very useful project. The objective of this project is to notify the user the amount of water that is present in the overhead water tank. Sep 27, 2015 · Ultrasonic Distance Measuring Sensor – HC – SR04 5v DC motor Circuit: First the motor shield will need to be installed. This shield does not make use of the digital pin 2, so I will use this for the ultrasonic sensor. I had to remove the header pin that would normally connect there so I could connect the sensor wire. In this project we show how to measure distances with the ultrasound sensor SR HC 04 connected to NodeMcu ESP 8266 and send the results to the smartphone, using Blynk application. There are a lot of projects referring to this subject, but few of them are concerning with the transmission of data...May 23, 2018 - Demonstration test on Ultrasonic Distance Sensor HC-SR04 with NodeMCU, Parking Car sensor https://drive.google.com/file/d/0Bzs8FwNnMHVBUjVJdUZKNmdlRFE ... NodeMCU ESP8266. Ultrasonic Sensor HC-05. Breadboard. Jumper Wires. The circuit is very simple as we are only using the ultrasonic sensor and NodeMCU. HC-SR04 ultrasonic sensor works on 5V, so if you connect it to 3.3V, it won't work.The modules includes ultrasonic transmitters, receiver and control circuit How to monitor the distance using an HC-SR04 ultrasonic sensor and ESP8266 NodeMCU connected to the AskSensors IoT cloud ESP8266 NodeMCU Workshop. Contribute to lvidarte/esp8266 development by creating an account on GitHub So right now I have it working 100% with 5v and ... May 23, 2018 - Demonstration test on Ultrasonic Distance Sensor HC-SR04 with NodeMCU, Parking Car sensor https://drive.google.com/file/d/0Bzs8FwNnMHVBUjVJdUZKNmdlRFE ... The kit includes two main Boards: Arduino Nano and NodeMCU mini, and 18 Kinds of the most popular used sensors and actuators such as Ultrasonic Ranger, OLED, stepper driver, etc. A breadboard and some jumper wires are also included to make this kit appropriate for starters using the kit by plug-and-play.
